摘要：

A microscale capillary Raman solution flow cell has been developed utilizing conventional high-performance liquid chromatographic capillary tubing. This cell is suitable for both liquids and gases over a wide range of pressures. The introduction of a liquid flow along the capillary allows the collection of Raman spectra of intensely coloured and highly absorbing solutions, eg. I2-CCl4, using 514.5 nm excitation. The application of this cell to the examination of supercritical fluids is demonstrated. The use of small cross-section capillary tubing (ca 10(-5) cm2) allows high linear flow-rates to be maintained with comparatively small solution volumes.
